I want a young gal.

I'm 74 years young. Been married to the same woman for 53 years. She has lost all interest in sex. I have lost all interest in having sex with her anyway. I tell her that I want one of them young whores we drive by at night all the time. She says go ahead, but if one of them girls give you some disease don't come crying to me. There's this young black girl, must be twenty or so, that's caught my eye. Hell, I don't care what color she is. I just want to run my hands up and down a naked young girl again. Is this normal?
